In the drawings, it will be seen that the machine consists essentially of two side frames (1) and-(2) arranged parallel with each other, and supported in an upright position by means of the five transverse stays (3).. Said frames are specially d'e signedwith means which allow of the suptwodouble' brackets (6) by means of pins passed .t hrougheyes of twolugs (7 projected from underpartof table-and an eye in each of: said brackets.

The other table 'is'carried 'by the cam spindle (8) projected through two bearing blocks (8") also-p'rovideduponthe under part, while the reduced end portions (8 and (9)of said spindle (8) are passed through eyes which are also provided in saidbrackets (6) secured to, and carried by the sliding base plates (10) and (11) respectively. Said tables (4) and (5) are arranged so that there will always be a clearance or parallel opening or space between they can'be adj ustably positioned beneath said rotating polishers,'-by the use of toothed side racks (12) and (13) removably secured'to lthe outer face' of the rails (15) (1S) and carried by the horizontal spindle-(20)." I

'Two pa'irs'of brackets-(22) and (23) are securely attached to the end portions of said sliding base plates and (11). One

pair of such brackets "(22) has tubular shaped bearings (24) and (25) projected outwardly therefrom to carry said horizontally arranged spindle (20) provided with the hand operating wheel (21). Each pair of said angle brackets carry two horizontal pinion shafts hereinafterdescribed, and also st'a'ys (25 and (23) which serve with said sliding-base plates (10) and (11) to comprise aslidable frame.

For the support'and adjustment of the tables (4) and (5) I provide the four double flanged extension rails (14), (15), (16) and (16 can be projected outwardly to provide an extended support for said tables (4) and (5) during the operation of polishing flat-surfaces. Each pair of rails is slidably positioned with their machined vertical faces, engaging each other, and slidably kept in position in the guide beds (26) and (27) by four flanged guide caps (28 (2'9), (30) and (30 removably secured to the outer faces thereof. These slidable rails havev inset toothed racks (31), (32), (33) and (34) situated one in the underpart of each rail as shown at Fig. 3. (35) and (36) are two horizontal operating spindles suitably positioned in bearings (37) of frames 1 and 2; the spindle (36) is provided with the hand operating wheel (38), and also two pinion wheels (39) and (40') operating with the other pinions in recessedpo'rtions (41) and (42) of said frames 1 and 2.

These pinion wheels (39) and (40) enracks (31) and ('33-); the object being to.

allow the inner rails (14) and (16) to be extended in one directionfor supporting the wide table (4) when employed under the rotating pol-ishers in the polishing of flat surfaces, as well asto allow the outer rails (15) and (17) to be moved in the opposite direction when thenarrow table (5) is likewise used beneath said rotating polishers. (47) and (48) are V shaped guides provided one upon each of said rails (15) and (16), to engage the inverted V shaped grooves (49) and (50) adaptably situated in the bottom partof the, slidable base plates ('10); and (11) to the extentpf the full length :of the latter, whereby the tables'will always be guidedto slide ina horizontal plane. V

The means for setting the narrow table (5) so that it will occupy the precise angle to allow of the beveled edges'bemg arranged exactly level with each other when the sheets out. actual contact as the proper setting of the world-wheels '(89) and worm pinions (88) in their respective positions enables such an arrangement to be carried out.

The means or feeding the polishing material to the surfaces to be polished-comprise the annular channel or gutter (112) situate concentric with the circumference of spindle (91). Communicating with this gutter and the face of rotating olishers are two passage ways (113) situate at an angle toward the vertical axis of said spindle (91) so as toiallow the olishing material to ex ude or flow central y to the polishing faces and on to the surfaces While being polished, so that the rotating polishers will be always what I term wet,

.The operation of. my machine is as fol- 1ow s:-

When motion is imparted to the belt pulley (84),,spindle (83) and worm pinion (82) the worm Wheel (7 6) operates the connecting rod (79) so as to reciprocate the frame (73). The driving shaft 86), belt driving pulley (87 bearings (85 as also a the rotating polishers, all move withsaid a rotat ng pinionsg zlo) and (46) engage the toothed racks (31) and (34) and operate the outer I reciprocating frame.

Although .saidframe has imparted to it a reci ,rocating movement, the worm pinions (8'8 operate the worm wheels (89) of spindles (91) of rotating polishers, which revolve at any desired speed.

The adjustment of either the wide or narrow tables (4) and .(5) to a position beneath the rotating olishers is effected by operating the hand wheel (21) and s indle (20), so that the pinions (18) and (19 will engage the toothed side racks 12 and (13) of the sliding rails. (15) and (1 When flat surfaces are to be polished the tables (4) and (5) and extension rails are slid by turning thewheel (38 and shafts (3:5) and 36 so as to rotate the pinions (39) and 40, for moving the inner rails 14), and 16 i in onedirection outwardly from the olishers; while the other geared rails (15)and (17) in the opposite direction so that a bed -;equal to the width of the combined tables will be provided.

There is therefore, each pain of proiected rails, one ofsuch rails engaging the respective guideways (49) and (50) of sliding base plates (10) and (11) with the guides (47) and 48), thereby allowing of the tables being always su ported and guided ina straight line. Sa1d tables (4) and (5) may be adjusted to lie horizontally, or at any desired angle, by operating the hand wheels. (72) and spindles. (69), so that the wormwheels (67) engaged by the worm pinions (68) will rotate the shafts (63) and (64). The rotation then given to said shafts imparts a vertical movement to the woman,

toothed racks (56), (57), (58 and (59) geared with the pinion teeth of s afts, either lfipwardly or downwardly, as the case may The pressure required for polishing the beveled edges is obtained by utilizing the weight of the rotating polishers, the hand lever gear and its attached parts; or if desired additional removable weights may be applied to the upper end portion of said spindles (91).,

Upon osclllating the bell crank levers (102) and (103) to a vertical osition, the rotating polishers will be in t e olishing position, but when horizontally p aced the polishers will be lifted up clear of the beveled edges or flat surfaces, in which case, the links (96) and (97 will remain ina disengaged position until again required for polishing.

The rotating polishers shown at Figs. 12 and 13 rotate with their arms (110) and (111) occupying the concavities in either side of adjacent polishers, thereby allowing them to operate with their centers closer to gether and at the same time relatively pro vide a greater amount of polished surface than would be possible with the use of circular or full diameter disks.

. I wish it to be here understoodthat I do not lay claim to any part of the operating means shown'for reciprocating the frame (73.) nor to the .parts comprising the hand lever gear; or the method of operatingv the right and left hand rotating polishers, but what I desire to claim is 1.
